Product Description


The EVAL-UFDC-1/UFDC-1M-16 is a simple evaluation board that allows users to quickly evaluate the performance of the Universal Frequency-to-Digital Converters UFDC-1 and UFDC-1M-16 without the need for external components and design various sensors systems. This 2-channel Evaluation Board lets use such ICs in 16 frequency-time parameters measuring modes, one generation (for a calibration purpose) mode and build various digital sensors and sensor systems including smart, self-adaptation and self-identification sensor systems. All existing frequency, period, duty-cycle, time interval, pulse-width modulated, pulse number and phase-shift output sensors and transducers can be directly interfaced to this evaluation board. The user can connect TTL-compatible sensors’ outputs to the Evaluation Board, measure any output frequency-time parameters, and test out the sensor systems functions.


Using the accompanying software, the EVAL-UFDC-1/UFDC-1M-16 evaluation board can be interfaced to any personal computer running Windows XP or later, via one of the serial computer’s com port RS232 or USB port (with an additional, optional USB to Serial (9-pin) DB9 RS232 adapter cable, for example, EMINENT USB to Serial Converter or others).

The software allows the EVAL-UFDC-1/UFDC-1M-16 Evaluation board’s functions to be controlled from a PC via an easy-to-use interface operating under Windows XP or higher. There are many ways to display evaluated results, such as the terminal programs for Windows, LabView and special software supplied with the Evaluation Board. The demo kit includes a CD with Terminal V1.9B and especially designed for the Evaluation Board the UFDC Eval Software V1.14. The software also lets to calibrate the converters and put a calibration constant into the converter’s memory.
